Reynolds number (RN) is given by (where h = Film coefficient, l = Linear dimension, V = Velocity of fluid, k = Thermal conductivity, t = Temperature, ρ = Density of fluid, cp = Specific heat at constant pressure, and μ = Coefficient of absolute viscosity)

RN = V²/t.cp

RN = hl/k

RN = μ cp/k

RN = ρ V l /μ

RN = V²/t.cp

RN = hl/k

RN = μ cp/k

RN = ρ V l /μ

Heat and Mass Transfer
Sensible heat factor is given by (where S.H. = Sensible heat, and L.H. = Latent heat)

(L.H - S.H)/S.H

(S.H + L.H) /S.H

S.H/(S.H + L.H)

S.H/(L.H - S.H)

(L.H - S.H)/S.H

(S.H + L.H) /S.H

S.H/(S.H + L.H)

S.H/(L.H - S.H)
